ROME — Police yesterday confirmed a link between Italian and Greek anarchists, saying the Italian group that sent parcel bombs to three Rome embassies was responding to an appeal from a Greek counterpart to step up attacks.

The Informal Anarchist Federation, an Italian group which claimed responsibility for sending mail bombs to the Swiss and Chilean embassies last week, also sent the mail bomb that was discovered at the Greek Embassy on Monday, Carabinieri Col. Maurizio Mezzavilla told The Associated Press.

The Swiss and Chilean bombs exploded Dec. 23, wounding the two people who opened them. The Greek bomb was safely defused.

In Monday’s claim of responsibility for the Greek package bomb, the group said it wanted to show solidarity with detained Greek anarchists and further their agenda of “revolutionary violence,” Mezzavilla said.

“We’re striking again, and we do so in response to the appeal launched by our Greek companions of the Conspiracy Nuclei of Fire,” the Italian group wrote in the claim, according to Mezzavilla. “For this reason, we’re sending this new attack to a structure that represents the Greek state.”
